I just got one too (elmar-M). tiny precious gem. It looks ridiculously sexy on m2.
I have purchased a new set of lenses:
21 2.8 Asph.
50 2.8
75 2.5
35 2 (7 element chrome)
it seems the cheapest (50 2.8) is the best among them 😀
i guess leica must rethink its sale policies, Noctilux .95 $900, Elmar-M 50 $10000 😉
